The invention discloses an aviation winch air door opening device. The aviation winch air door opening device comprises an air door arranged on a power cabin and an adjusting assembly used for adjusting the opening angle of the air door. A fixing support frame is arranged on a main shaft of the power cabin in a sleeving mode and is used as a basic installation component of the aviation winch air door opening device. A motor and the fixing support frame are fixedly connected through a motor gland; a magnetic hysteresis brake is arranged on the fixing support frame; the rotating speed and the torque of the motor are controlled through the magnetic hysteresis brake; an adjusting screw sleeve is arranged outside the motor in a sleeving mode; in addition, an adjusting screw nut is arranged on the adjusting screw sleeve; an air door connecting rod arranged on the adjusting screw nut is movably connected with the air door; and the adjusting screw sleeve is driven to rotate by an output shaftof the motor, so that the adjusting screw nut is driven to move horizontally, the air door connecting rod is driven to push the air door to open, and goal of precisely controlling the opening angle ofthe air door achieved.
